Brief
of
introduction:
The
3A
UBEC
is
an
advanced
switching
DC
-
DC
regulator whlch will
be
supplled a constant 3A
or
more with short bursts
of
up
to
SA
. The
3A
UBEC
supplied with
2-85
lipo battery
pack
and
output
as
consistent
safe
power for your receiver, gyro
and
servos
.
It
is
very suitable for big
electric
RC
models
such
as
fJXed
-wlng aircrafts and helicopters which use more than 45
Iithium battery.
BTW
this
JA
UBEC
also
added
a

Although
we
have trled our
best
to
reduce
the electromagnetic lnterterence
caused
by
switch model
UBEC,
it
may
still
cause
some interference to the recelver. So pl
ease
lnstall the fllter (ferrlte ring) far away from the
UBEC's
maln board,
ana
DON'T
Stac

Piease
put the whole
UBEC
as
far
as
possible away from
the
rece
